To a/ZZ whom. it may concern.:

' Be it known that I, ROBERT H. H. HUNT, a citizen of the United States, residing in the city and county of San Francisco, State of California, have made and' invented certain new and useful Improvements in FullingllIills; and I do hereby declare that the following is a full,"clear, and exact description of the same, reference being had to the accompanying drawings.

yMy invention relates to improvements in machinery for fulling cloth in the process of its manufacture; and it consists in passing a length of cloth in a double or folded condition around a drum or cylinder and between its face and the faces or peripheries of a number of bearing-rollers having independent bearing or working faces to engage with and act upon each fold or turn of cloth on the drum, the operation being such that vthe cloth is pressed, rolled, and kneaded or worked by the rollers while running upon and being carried around by the drum.

It consists, also, in carrying and guiding the length of cloth in a number of spiral turns around the drum by means of peculiarly-arranged guide-rollers.

'It consists, also, in forming a drum with clothcarrying grooves and in guiding the clothfrom one groove to the other in a continuous manner from end to end vof the drum, so that its ends being joined together it is carried in the form of an endless band or belt many times through the machine.

It consists, also, in means for regulating the slack of the cloth and controlling the amount of shrinkage.

It consists, also, in combining with the fulling-drum, stop-motion to throw off the power` and stop the machine at the end of any required number of revolutions.

The following description' fully explains the nature of my said improvements and the manner in which I vproceed to construct, apply,

use, and operate them, the drawings being referred to by figures and letters-#that is to say: j

vFigure 1 is a front elevation of my improved mill, one-half of the case being thrown open rollers. Fig. 7 is a detail View, showing the construction of the slip-motion.

A represents a large cylindrical drum, supported in horizontal position within a suitable inclosing box or case upon journals B B. Around it are placed a number of rollers, C C, and between its periphery and the faces of these rollers the cloth to be fulled is carried by the rotation of the drum on its axis. The

cloth being folded or twisted into a band is laid in regular spiral turns over the face of the drum, and its two ends are joined together, so that an endless belt of cloth is formed. Suitable means are employed to hold and guide the cloth upon the drum and cause it to run in regular spiral turns from one end to the other, so as to pass under and receive the action of all the bearing-rollers. The best form of drum for this purpose is one with a series of channels or grooves, a a., around its periphery running parallel with one another and at right angles to its axis. It can be constructed of a number of disks or sections placed together upon a central core or shaft, and held together by any suitable locking device-such as a threaded nut or collar screwed on the shaft against the outside sectionsor it can be a single structure with the grooves cast or turned init. The grooves may be either of rectangular or of semicircular form in cross-section. The object of placing these grooves parallel with one another is to provide for bringing the cloth in proper position and relation with the worhingfaces of the bearing-rollers C, and to have the shafts of these rollers run parallel with the axis of the drum. The cloth being wound across the ridges and depressions in the drum, the rollers C press it into the depressions a and thus worlr it. The edges of the ridges are not sharp so as to cut the cloth when pressedagainst them'. v

To lay a length of cloth yin a spiral manner around the drum I place beneathittwo horizontal guide-rollers, G G, under which l the cloth from one groove at one side .of the drum is carried across to the opposite side to enterl These rollers are placed di- Y the next groove.` agonally with respect tothe axis of the drum to give this oblique .or spiral turn to the cloth. Theyare mounted in adjustable-side bars,.g

g, so that they can be raised and lowered to' regulate the slack of the cloth, for which purpose the bars g, supporting their journals g g are movable vertically atxone end, andcany be set up or down, as required, to bring thel rollers nearer to or farther from the drum.` Insteadv of two guide-rollers, a vsingle one of larger diameter could be employed. This wouldj take up more room beneath thedrum, however, and in practice would not operate so well in conjunction with the other washing apparatus of the mill as would the arrangement of the two rollers. v

The rollers C C, placed around the drum,

are mounted in adjustable bearingsto regulate and change their pressure and contactwith the cloth. The bearings of all the rollers are moved and set together and with a uniform movement. Such a means of. adjustment is shown irl-Figs. 1 and 2, and consists of boxes hhior the roller-shafts h heldin sliding bearings h2 in the sides of the machine, and each box connected by means of rods h3 with arms or spokes H of stiff spring-steel projecting from a sleeve'or.k

hub, X. The hub X is loose and capable of turning freely uponv a box, w', through which the shaft of the drum runs, and a segment-arm, lY, projecting from the hub, lgears with a pinion, Z. This mechanism is duplicated at the `opposite side of the machine; and the two pinions Z Z are mounted on a single shaft extending across the machine, so that by meansl of a wrench or crank-handle the pinions Z canbeturned and rotation of the hubsfX effected in either direction. Movement of this hub. in one direction will therefore setup the roller-boxes h and in the opposite direction willldraw them y The faces of these rollers are formedy of independent bearing-surfaces f f, and arev produced either byv forming the roller of a se-' down ries of projecting disks separated by collars of smaller diameter xed upon a central shaft, or

by casting or forming them integral with alter-y nate projecting rims and grooves.

to the distance between the cloth-ycarrying grooves when combined with .such a drum, `s"of that each turn of cloth will have a diskor facev bearing upon it across the entire length' 'of thek drum.4 Different shapes. and forms aregiven to'these working-'faces to producey different vaction and effect upon the cloth,"and I do not limit my invention to any particular form or; construction, as itV maybe found that one s hape or kind vis'better than another on different kinds, thicknesses, or grades4 of cloth to 'be treated. rl'Jhose shown at F, withat edgesor workingfaces,-have a regular pressure across The' dis-,f tances between the projecting faceswill be equalV the folded cloth onthe drum, .and those at f, with convex rims, willbear'more upon and along oneline or portion of the clothand have a tendency to turn or twist the cloth, particularly if the groove in thedrum is concaved c instead of `nat, while those at f with knobs or, protuberances, as at f2, will produce a kneading action to felt orwork the bers together. `These rollers "are, placed in regular order with their working-faces in line, as in Figs. l and v2, or they are arranged to work alternately, as in Figs. 5 and 6, the facesof one roller working in different .grooves from those of the next roller,\and a gang ofrsuch rollers being arranged around the periphery of the drum, the cloth in its movement around the drum is brought many times in contact with these differently-formed Vroller-faces dur- 'to runin regular lines over therdrum. There arealso other rollers placed beneath these rollers atthe botto'miofthecase to control the direction'of travel'and the tension of the 'Y cloth. These consistl off-the upright guide-rolls J, one of 'Which'is mounted in adjustable bearings to form a -tensio'n device so that its position can be 'shifted to v-and fromthe other roll, anda less 'or greater' amount of tension thereby produced on ythe 'length ofcloth. Thisy enables the amount ofshrinkage yto becontrolled and adjusted, as desired. For this-adjustment'the shaft of the'roller 4is set in a slotted bearing in the bottom of the case to be'movable to and 'fromthe center.

vConnected with this r`clothfulling.mechan- 'ism l'in the same case, I vapply a Soaping and washing apparatus, -byme'ans of which the two operations of fullirg and'washing can be performed upon the cloth without removing it from the drum. I propose to make the-washing andsoaping-apparatu's the subject of a 'separate application for patenuana donor claim itl in this patent; butI will describe 'it herein. This yapparatus consists 'of a perfof'rat'ed conductingtube, K, led into' the vspace.

betweenthe two guide-rollersGG,`and connecting on the utside' of Vthe ease 'with hot and cold water' and ,'soapsupply pipes no p, 'provided with :suitable 'controllingicocks o 'p'. Thel positionof this conductor is directly over thetu'rn's of the cloth that pass under and ac'rfoss from' one'roller' Gto the' other, and'its perforations are upon the under sidel to direct the water' orfsoap against the cloth passing bevmath.

A Wringer attachment, Qfis placed in such y relation to one of the .guide-rollers G that it vcan be thrown into action When'required and ing the distance between the roll andthe diagonal guide-roll. 'The floor of the case is inclined toward the outlet u to direct the Water to that point of discharge, and a sieve or strainer bottom, V, is laid across and just over the floor to catch and let the soap and Water pass oil", but retain the flock or particles thrown off from the cloth. The application and arrangement of these rolls are clearly shown in Figs.'v

2 and 4 of the drawings.l

To make the operation of the machine en tirelyy automatic I connect the driving mechanism with the i'ulling-drum by means of--a stop-motion, which is so constructed that it can be set to disconnect the power and stop the machine when thedrum has made a given y number of revolutions. This consists oi' a beltshifting lever, 1, pivoted at 2 to the -outside of the frame :in suitable relation to the pulleys T T. It is moved in one direction to unship the belt by a spring, 3. To hold it out of .action and retain the belt on the fast-pulley a catchrod, 4, movable up and down in the bracket 5, is caused to engage with a hole in the lever l. To draw up this rod and release the lever l a disk, mounted on a shaft, 6, is provided with a stop-pin, 7. This shaft 6 is rotatedA by means of a paWl-and-ratchet mechanism through the medium of the gear 8, the Worm- Wheel 9, a ratchet-wheel, 10, on the Wormwheel shaft Il, and the ratchet-lever l2. Movement of this lever. is effected once during each revolution of the drum by means of a pin, 13, fixed on the side of the pulley T inline With the end of the lever l2. This construction is shown in Figs. 3 and 7 ofthe drawings. The proportions of the Worm-'Wheel and tooth- Wheel 8 are such that a certain number of revolutions of the drum will produce one revolution of the disk, and the pin 7 Will vthen be brought around beneath the end ofthe triprod and raise it out of the'notch in the beltslipping lever.

The disk L is movable upon the shaft 6, so that. at the beginning of opera-tion the pin 7/ canl be set to engage with the rod 4 at less number of revolutions and stop the machine.

To regulate the temperature within the mill and bring it to any desired degree of heat, I place a coil of pipe, N,\vithin the casej ust above 6o the door, and make connection on the outside with ahot-Wate'r or steam supply. This pipe may be the ordinary hot-water pipe for supplying the pipe I). Y

Having thus fully 'described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a fullingmill, a druln for carrying and presenting the cloth tothe action of fullingrollers, and means combined therewith for 7o holding and guiding a length of cloth in an inclined or spiral direction upon the drum from one end to the other, substantially as described.V
